How does it fail? I wrote some code that creates a directory on the
sdcard, and writes files to that directory. I can't remember that I
had any problems at all.
.. I'm however root on the phone, but I hope that that doesn't matter.
File directory = new File("/sdcard/mydir");
if (!directory.exists()) {
directory.mkdirs();
}
FileOutputStream out = new FileOutputStream(directory.getPath()
+ "/
filename.txt");
//Write to out
